The Timberline is ridden by Race Whippets and Weekend Warriors alike and feature great strength and durability with a lightweight frame and great reliability. This means these bikes are equally at home on the singletrack, the sprint for the finish line or a Sunday thrash with your friends.

It's also suited to the leisure rider who wants to experience the thrills of off-roading either on the local trails or tracks, or who wants a bike with greater versatility (on/off road).

From the all-day ride ability of the Sensor, to the classic aluminium hardtail approach of the Avalanche and Aggressor, there's a trail bike for whatever you ride however you ride it.

Each bike is fully built, tested and tuned by Wiggle's team of qualified bike mechanics to ensure your bike arrives in perfect condition.

Supplied with basic flat pedals although Wiggle recommends using dedicated clip-in pedals and shoes to get the most from your road bike

About Hard Tail Mountain Bikes

If you are looking for a mountain bike that can comfortably negotiate bumpy, cross-country, singletracks yet still be quick and nimble on the road, then a hardtail bike is for you. Hard tail mountain bikes have front suspension, weigh less and are more pedal efficient when the terrain is smooth, than full suss bikes. A good number of single track racers still use hardtails for these reasons. At wiggle, we stock a wide variety of hardtail mountain bike brands including Felt, Focus, GT, Kona, Mongoose, Saracen and more. So if you are searching for superb, quality spec hardtail mountain bikes at great value with a legendary service to match, then you've come to the right place.

About the GT brand

GT Bikes, based in Southern California, has been in the business of making great bikes since 1972 when Gary Turner launched one of the first performance BMX race bikes.
Developing world class bikes in conjunction with the world’s best BMX rider such as Greg Hill, Eddie Fiola, Jamie Bestwick, Clive Gosling and Dave Mirra, GT grew into one of the biggest brands.
With a BMX heritage and based in California the MTB scene was the perfect addition in the late 80’s . GT used the same model of developing performance bikes with the best riders, pioneering new suspension technology and the use of carbon fibre in MTB frames. Winning numerous World Championships in downhill and cross country racing with legendary riders such Nicholas Vouilloz, Steve Peat and more recently Atherton Racing, with Dan Gee and Rachel Atherton.
Hans “No Way” Ray has been one of the figurehead of GT’s longstanding team rider program, setting the record for longest sponsorship deal of 26 years and counting.
It hasn’t always been about dirt, in the mid 90’s GT took there carbon technology and build track bikes for the USA Olympic team, the bike was later banned for being too fast. GT latest crop of Enduroad Grade models play perfect testament to the brands heritage across, dirt, road and track.

Great Value Bike
Great value for an entry level 29er. Some of the components are budget, but these can be upgraded as they wear. Frame is GT high standard so a good starting point.
Service from Wiggle was, as usual, perfect.

Bigger is better!
The main purpose of my bike is primarily the 2 mile commute to work, my previous bike was a 26" GT Ricochet MTB with road tyres fitted. I'd been eying this bike for a since it came out, (the classic GT silver, blue and yellow appeals to the 80's BMXer in me!), money was an issue at the time, but I couldn't refuse when I saw it was in the sale.
I wanted a 29er just for something different and I'd read about how they were slow to get up to speed but like a steam train once they're going and I can honestly say that's the case! Once zooming along, this bike is way faster than my 26er. If only traffic didn't slow down so frequently.
The bike itself is as I've come to expect from GT (or any mainstream brand). Well made, but with some components, like tyres or pedals, that you know you'll change sooner rather than later. I dispensed with the plastic platform pedals provided and fitted some DMR V8's that I had sitting about and I got a flat tyre within two days, so bought some Kevlar liner strips for the tyres.
Overall, I'm really pleased with the bike. It's massive compared to my last ride but not in any way that causes a problem. If there is a drawback, it's that it looks much more expensive than it is. So keeping it out of the hands of thievery might be a challenge. I've got a good lock though, so hopefully I'll enjoy the bike for years to come!

Answer:

I can confirm that the specification on the two bikes is similar as is the build quality, the main difference is that this Timberline is a 29" wheel where as the Aggressor is a 26" wheel making the Timberline slightly heaver.
